In addition to money or other compensation, other motives for selling sex may be important in a welfare country such as Sweden. The aim of this study was to carry out an exploratory investigation of adolescents’ motives for selling sex in a population-based survey in Sweden. A total of 5839 adolescents from the third year of Swedish high school, mean age 18.0 years, participated in the study. The response rate was 59.7% and 51 students (0.9%) reported having sold sex. Exploratory factor analysis and hierarchical cluster analysis were used to identify groups of adolescents according to underlying motives for selling sex. Further analyses were carried out for characteristics of selling sex and risk factors. Three groups of adolescents were categorized according to their motives for selling sex: Adolescents reporting; 1) Emotional reasons, being at a greater risk of sexual abuse, using sex as a means of self-injury and having a non-heterosexual orientation. 2) Material but no Emotional reasons, who more often receive money as compensation and selling sex to a person over 25 years of age, and 3) Pleasure or no underlying motive for selling sex reported, who were mostly heterosexual males selling sex to a person under 25 years of age, the buyer was not known from the Internet, the reward was seldom money and this group was less exposed to penetrative sexual abuse or using sex as a means of self-injury. In conclusion, adolescents selling sex are a heterogeneous group in regard to underlying motives.  相似文献

This investigation identifies demographic, media, and social correlates of verbally aggressive communication in adolescence. Mail surveys were completed and returned by 2,300 adolescents between the ages of 13 and 15. These adolescents were asked about the prevalence of verbal and physical aggression, the context in which it occurred, demographics, and the interpersonal and media influences in their lives. The results indicate that verbal aggression is widespread, that committing and experiencing verbal aggression is largely reciprocal, that there is a strong relationship between committing verbal and physical aggression, and that peer social influence and listening to violently oriented music are mildly related to verbal aggression in adolescents. These findings suggest more resources should be allocated to teaching adolescents to understand and control verbal aggression. Further, they provide important answers to many prevention and intervention programmatic questions, including context, content, and targeting concerns. Since the negative consequences of verbal aggression are severe and long lasting, decreasing this destructive communication behavior should significantly improve the lives of many adolescents. These and other practical implications are expanded upon and discussed.  相似文献

To analyze the factors associated with the types of violence against adolescents reported in Pernambuco, Brazil, from 2009 to 2012. Prevalence study conducted through an electronic database from the Violence Surveillance Official System in a population of 5259 adolescents (aged 10–19 years). Poisson regression was used, with significance level at 5%. There was a significant increase of 204% in the number of violence reports, and the number of reporting units increased by 92.6%. When separately evaluated, physical violence was the most prevalent type, accounting for 44.7% of the reports. Taking as independent variables the age range of 15–19 years, female, having no disability, and public roads as place of occurrence, the positively and independently associated factors were: male gender (OR 1.5, 95% CI 1.4–1.6) with physical violence; having deficiency (OR 1.7, 95% CI 1.5–2.0) with psychological violence; age range of 10–14 years (PR 2.4, 95% CI 2.2–2.6) with sexual assault; and male (OR 3.9, 95% CI 2.0–7.5), having disabilities (PR 4.6, 95% CI 2.7–9.7), and occurrence in residence (PR 2.8, 95% CI 1.3–6.1) with neglect. Age between 10 to 14 years was associated with the occurrence of sexual assault; male with the occurrence of physical violence and neglect; having disabilities with psychological violence and neglect; and occurrence in the residence was associated with neglect.  相似文献

Published in 1951,The Catcher in the Rye encapsulated teenage angst. Some time ago David Belbin mused about the influence of Catcher on the proliferation and popularity of YA literature. Salinger's recent death has sparked a renewed interest in his work and more attention on Holden and his inheritors. This article discusses how five recent adolescent novels, with male protagonists, mirror Holden's adolescent paralysis. They exist in a liminal state between childhood and adulthood, attempting to understand the phonies around them. These protagonists help define the nature of the ‘lost’ adolescent in the current golden age of YA literature.  相似文献

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.  相似文献

The aim of the study was to compare and contrast habitual physical activity (PA) profiles and muscular fitness in schoolchildren from northern and southern regions of England. Data were collected from two secondary schools in the north east (NE) of England. The study procedures followed methods employed by the East of England Healthy Hearts Study in 10–16-year-old boys and girls based in the south east (SE) region of England and data were compared. Habitual physical activity (PAQ-A), vertical jump test, and hand-grip (HG) strength were assessed. We converted raw scores from all assessments to age- and sex-normalised z-scores. We recruited 597 children (58% boys) in the NE and compared findings to 597 age- and sex-matched boys and girls from the SE. Boys in the SE had significantly stronger HG scores, jumped higher, were more powerful (mean peak power: 2131?W vs. 1782?W; P?P?P?相似文献
